What’s the difference between liquid lanolin and solid lanolin (the sticky stuff)?
Their source is the same, the contents different. Their purpose is the same, the effectiveness different. Both my liquid and solid lanolin are extracted from sheeps wool. Both are pesticide and detergent free. Liquid lanolin has been centrifuged to remove the wax from the woolfat/oils. Both are used for lanolizing wool but solid lanolin, because it retains the waxy component, is a more effective water-proofer. Many people find, especially on processed wool, that exclusive long-term use of liquid lanolin is inadequate and that periodic lanolizing treatments with a form of solid lanolin are required to keep their wool at peak function.
